Well, isn't that a happy little question! To find the mass of 42.6 moles of silicon, you'll need to multiply the number of moles by the molar mass of silicon. The molar mass of silicon is approximately 28.0855 grams per mole, so when you multiply that by 42.6 moles, you get a mass of about 1197.6 grams. Just like painting a beautiful landscape, it's all about following the right steps with a touch of joy and curiosity!
1 mole Si = 28.0855g Si 245g Si x 1mol Si/28.0855g Si = 8.72 moles Si
The mass is sometimes informally called the "amount of substance", though this is not very precise. The SI unit for mass is the kilogram.
Atomic Mass of Fe: 55.8g/mol Atomic mass of O: 16g/mol Molecular mass of Fe2O3: 2(55.8)+3(16) = 159.6g/mol mass = Molecular mass x number of moles mass = 159.6g/mol x 0.7891mol = 125.94g

The SI unit for molar mass is grams per mole (g/mol). It represents the mass of one mole of a substance, which is a convenient way to compare the masses of different substances on a consistent scale.
For this you need the atomic mass of Si. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.2.61 grams Si / (28.1 grams) = .0963 moles Si
Mol is an official unit of concentration in SI, not of mass.The transformation of a concentration expressed in mass per volume in a concentration in moles is at your choice.
To find the mass of a Si6F12O6 molecule, we first calculate its molar mass by summing the atomic masses of its constituent elements: silicon (Si), fluorine (F), and oxygen (O). The molar mass is approximately 6(28.09 g/mol) + 12(19.00 g/mol) + 6(16.00 g/mol) = 468.54 g/mol. To find the mass of a single molecule, we divide the molar mass by Avogadro's number (approximately (6.022 \times 10^{23}) molecules/mol), resulting in a mass of about (7.77 \times 10^{-22}) grams.
Atomic Mass of Fe: 55.8g/mol Atomic mass of O: 16g/mol Molecular mass of Fe2O3: 2(55.8)+3(16) = 159.6g/mol mass = Molecular mass x number of moles mass = 159.6g/mol x 0.7891mol = 125.94g

To find the mass of 0.50 mol of aluminum foil, we first need the molar mass of aluminum, which is approximately 27 g/mol. Therefore, the mass can be calculated using the formula: mass = moles × molar mass. For 0.50 mol of aluminum, the mass would be 0.50 mol × 27 g/mol = 13.5 grams.
Atomic mass of Fe: 55.8g/mol Atomic mass of O: 16g/mol Molecular mass of Fe2O3: 2(55.8)+3(16) = 159.6g/mol mass = Molecular mass x number of moles mass = 159.6g/mol x 0.7891mol = 125.94g
To find the mass of 0.200 mol of aspirin (acetylsalicylic acid), you first need its molar mass. The molar mass of aspirin is approximately 180.16 g/mol. Therefore, the mass of 0.200 mol of aspirin is calculated by multiplying the number of moles by the molar mass: 0.200 mol × 180.16 g/mol = 36.03 g. Thus, the mass of 0.200 mol of aspirin is about 36.03 grams.
Atomic Mass of Fe: 55.8g/mol Atomic mass of O: 16g/mol Molecular mass of Fe2O3: 2(55.8)+3(16) = 159.6g/mol mass = Molecular mass x number of moles mass = 159.6g/mol x 0.7891mol = 125.94g
